Patented Mar. 1o, 1931 Uni-TED STATES HARWoon C. Ross, or MALVERN, oi-rro TRIM TILE My invention relates to trim tiles, which may be made of refractory material, molded `of concrete, or otherwise formed of preferably lire resisting material. v

[When such tile are used in building constr etion, for exampleifor interior partition walls, it is frequently necessary Vto secure metal lath or other members to the tile for trimming and finishing purposes.

The objects'ofV the present invention include the provision of simplified means .permitting the securing of members to the outer surfaces of the trim tile, by nailing.

These and ancillary objects are atta-ined in the present invention by a construction and arrangement which may be set forth in general terms as including a trim tile having one or more cylindric externally opening grooves therein, and interengaging nailing strips adapted to be rotatably entered into and engaged with the grooves.

A preferred embodiment of the improvements is hereinafter set forth in detail, and is illustrated in the accompanying drawings forming part hereof, in which Figure 1 is a perspective view illustrating several of the improved trim tile provided with the rotatable interengaging nailing strips;

Fig. 2, a fragmentary transverse sectional view, illustrating one of the segmental nailing strips about to be engaged in the externally opening groove; and

Fig. 3, a fragmentary view similar to Fig. 2, illustrating the segmental nailing strip rotated into securing and engaging position in the groove.

Similar numerals refer to similar parts throughout the several views.

In Fig. 1, a plurality of the improved trim tile 10 are illustrated as being built up to form one side of a` doorway. Each of the improved tile 10 has formed preferably in each of its opposite external surfaces 11 and 11, a plurality of longitudinally extending externally opening cylindric grooves 12, each groove having a segmental transverse cross section, and the longitudinally extending out- Ward opening 13 of the groove thus being less in width than the diameter D thereof.

i Application filed Gctober 2, 1928. Serial No. 309,754.

Nailing strips lll are provided for being rotatably engaged in the grooves; and each nailing strip 14 is in the form of a length of material, preferably wood, which has a segmental transverse cross section 15, the cylindric portions of which fit the cylindric portions of the grooves 12, and the minimum cross sectional width D of which, between the straight edge 16 and the cylindric edge 17 thereof, is less than the transverse distance across the opening 13; whereby each of thenailing strips 14 may be inserted into any of the cylindric grooves through. its opening 13, as illustrated in Fig. :2, and rotated to the engaged and secured positionl illustrated in Fig 3.

The nailing strip is thus ready for receiving` nails therein for securing metal lath or other desired members to the tile.

In order to best attain. the benefits ofthe present invention, l e transverse distance across theopening of each groove, should be greater than the depth of the cylindric groove, so that the segmental strip maybe easily inserted in the groove.

I claim:

1. In combination, a tile and the like having formed therein a longitudinally extending cylindric groove having a longitudinally extending external opening therefor in a surface of the tile, and a nailing strip having a segmental cylindric cross section secured and engaged within the groove, the diameters of the cylindric portions of the nailing strip and the groove being substantionally equal, and the minimum cross sectional dimension of the nailing strip being less than the transverse distance across the external opening of the groove, whereby the nailing strip may be inserted transversely through the opening into the groove for being secured therein.

2. In combination, a tile and the like having formed therein a longitudinally extending cylindric groove having a longitudinally extending external opening therefor in a surface of the tile, and a nailing strip having a cylindric surface and a flat surface secured and engaged within the groove, the diameters of the cylindric portions of the nailing strip and the groove being Substantially equal, and the diametraldistance from the flat surface of the nailing strip to the cylindric surface thereof being less than the transverse distance across the external open- `ing of the groove, whereby the nailing strip may be inserted transversely through the opening into the groove for being secured therein. y

. 3. VIn combination,a tile and thelike having formed therein a longitudinally extending cylindric groove having a longitudinally lextending external opening therefor .finfa 'surface of the tile, and a nailing strip having a segmental cylindriecrosssection secured` and engaged within the groove, the

' transverse distance acrossthe external openingl at the surface of thetile being greater lthanthe depth ofthei'groove from the surface of the tile, whereby the nailingV strip may ,be'inserte'd transversely Vthrough the openingy into the groo-ve for being secured therein.

' Incombination, a tile kandthe like having formed therein a longitudinally extending cylindric groove having'a longitudinali De ly'/ extending external opening therefor in a surface of the tile, and a nailing strip havin a longitudinally ,extending cylindric groove having a longitudinally. extending external opening therefor in a surface of the tile, lthe transverse distance across the external opening at the surface ofthe tile being greater than the depth of the` groove from the surface ofthe tile, whereby a seg-V 'mentall cylindric nailing stripniay be inserted transversely through the opening' into- 'Y the groove for being secured therein.

Y 7. A tileand--the like having formed there- Vin a longitudinally extendingV cylindric :groove whose longitudinal axis is spaced a less distance from the surface of the tile than the vlength of-a` radius of the groove, whereby a longitudinally extending; opening for the groove is formed in the surfaceof the tile, kand the transverse distanceacrossthe externalopening at `the surfaceof the :tile being ,greater than the depthv ofjthegrojove fromthe surface of thetile, wherebya segmental cylindric nailing strip may bev inserted transverselythrough the opening into thegroov'e for being secured therein.
